ESP: Using our resources to help preserve the world For over 30 years, Environmental Systems Products (ESP) has focused on one goal - providing the vehicle inspection and maintenance industry with state-of-the-art equipment and solutions for vehicle emissions programs throughout the world.


ESP understands that emissions testing is not a one-size-fits-all enterprise. Different states, countries and fleet managers have different requirements and testing needs. ESP not only provides turnkey emissions testing systems, but we also manufacture equipment for all different types of testing.


A true benefit we offer our customers is our capability to implement a broad array of technology and services to help you meet all governmental requirements for clean air.


ESP has recently entered the final phase of their merger with Systech International that began last year, the companies are assuming a single legal identity -- Opus Inspection, Inc.  Together, they are the only fully vertically integrated company in the vehicle inspection industry.  For more information, read the press release.
